If you're absolutely, positively certain they are queenless you should have time to do a combine RIGHT NOW in OH.
However, I'm uncertain on how to do so with a TBH :-\ other than just simply transferring the bars to another TBH (room permitting? that's the big Q) and fitted with perhaps a "double screened follower board" for a few days to prevent fighting among the 2 colonies. I used to have such a thing (homemade, designed to fit my TBH) around here but you should build some (follower boards) for these kinds of issues and double screen at least one for combines. Shouldn't be too hard to fix something up (to keep them separated) in an hour or so with a saw though. Good luck.
Personally I use Langs and LONG Hives these days, gave up TBH a few years ago.
